CAN-CLEANER;

Specification of Letters Patent.

Patented May 19, 1908.

Application filed December 14, 1907. Serial No. 406,555.

To all whom it may concern:

Be it known that I, KITTIL HAGEN, a citizen of the United States, residing at Webster, inthe county of Day and State of South Dakota, have invented a new and useful Can- Cleaner, of which thefollowing is a specification.

This invention relates to machines for 'washing milk cans and similar containing vessels and has for its object to provide a strong, durable and thoroughly efliclent machine of this character for scouring and cleaning the interior walls of the cans.

' transverse sectional view of the same.

A further object of the invention is to provide a can washer lHCllldlIlg a supporting frame having a can holder mounted for rotavtion thereon and provided with a cleaning element or brush which bears against the interior walls of the can when the holder is rotated thereby to thoroughly clean the same.

A further'object is to provide Im roved means for clamping the can in the older, and means for locking the brush a ainst accidental displacement during the c caning operation.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efliciency.

, Further obiects and advantages will appear in the fol owing description, it being un-- derstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims.

n the accompanying drawings forming a part of this specification: Figure 1 is a slde elevation of a can Washer constructed in accordance with my invention. Fig.'. 2 is a transverse sectional view of the same. Fig. 3 is a side elevation of the cap of the can holder. Fig. 4 is a front elevation of the same. Fig. 5 is a side'elevation of the cleaning element or brush. Fig. 6 is a top plan l j ect matter of the present invention includes a supporting frame comprising corner osts y longitudina and or uprights 5 connected Fig. 7 is a.

transverse bars 6 and 7 and provided with transverse top lates 8 and 9 which latter,

are bolted or 0t erwise rigidly securedto the upper ends of the corner posts, as shown.

Secured to the transverse top plate 9 is a Secured to vthe inner end of the stub shaft 12 is a cylindrical disk or head 13 having its inner and outer faces reinforced by transcasting 10 provided with spaced bearings 11 in which is journaled a stub shaft 12.

verse strap irons or bars 14 and 15. The op-v osite ends of the strap iron 14 are bent roduce terminal fin ers 16 to aterally to which are bo ted or otherwise rigid y secured longitudinal clamping arms 17, there being a similar attaching finger, 16, formed on one end of the brace 15 for engagement with a corresponding clamping arm, as shown. The opposite end of the transverse brace 15 is provided with a relativel short finger 18 which bears against and orms aguide for the milk can, indicated at 19.

The milk can 19 is supported between the arms 17 with its large end bearing against the head'13 of the can holder and with its reduced end or neck engaging anti-friction rollers 20 'ournaled on suitable pins extending latera y from the top plate or bar 8. Surrounding the longitudina arms 17 of the can holder. is a clamping band or member referably formed in two sections 21 and 22 aving' their adjacent ends pivotally connectedrby a loop or link 23. The long section 22 is secured to the'exterior faces of the arms 17 and is provided with elongated slots 24 in which are seated screws or similar fastening devices which serve to secure said section in osition on the arms and at the same time a ow a limited longitudinal movement of the strap section with reference to said arms. Y a

Secured to the free end of the relatively short strap section 21 is a link 25 on which is pivotally mounted a locking lever 26 having a hooked terminal 27 for engagement with a link 28 carried by the free end of the strap section 22 whereby the strap sections may be clamped in engagement with the can and thus prevent accidental displacement of the same when the holder is rotated. One end of the locking lever is preferably formed with a terminal lug 29 which engages a bail 30 ivoted onthe strap section 22 when the 'ng lever is in operative position so as to event the strap sections from becoming r detached. Secured to the inner faces of the ing element or brush 36.

longitudinal arms at the strap section 22 are spacing blocks 31 which bear against the intermediate portion of the can),. there being cushioning members 32 preferably formed of rubber or other yieldable material secured to the ends of the arms 17 for engagement with the adjacent exterior surface of the can, as shown. Secured to the u per surface of the end plate 8 is a block 33 aving a transverse tion 0 the reduced extension 35of the cleaned at 37 on the extension 35 is a locking late 38 adapted to extend beneath spaced ocking' bars .or guides 39 secured to the block 33 on opposite sides of the transverse groove 34 when the lockin plate 38 is rotated by manipulating the andle 40. The lower wall of the groove 34 is formed with a seating recess 41 for the rece tion of the pivot 37 so that the locking mem er may be rtitated without danger of binding on the top p ate 8. I

The cleaning element or brush 36 is preferably formed of a plurality of brushsec' tions arranged to conform to the interior of the can and rigidly clamped together by a s'trapiron 42, the reduced extension 35 of said stra iron being provided with a depending lug 3 which bears against the inner face of the transverse top plate 8 and serves to limit the longitudinal movement of the cleaning element and also to properly position the same within the can.

One end of the stub shaft 12 is provided with a terminal crank 44 by means of which the holder may be, rotated during the cleaning operation. The face of the short strap section 21 is preferably provided wit spaced blocks 45 which bear against the exterior walls of the can so as to prevent denting or otherwise injuring said walls when the clamping member is ad usted.

Attention is here called to the fact that the braces 14 and 15 intersect at the center of the disk or head 13 and thus not only serve to reinforce and strengthen the head but also form a supportfor the inner end of the stub shaft.

In operation the can is filled with a quantit of hot water and said can laced in the ho der and the clampin ban adjusted in a the manner before descri ed, the brush having been reviously inserted within the can. The han 1e 40 is then partial] rotated which causes the opposite ends of t e locking plate 38 to engage t e lower faces of the looking bars 39 and thus prevent accidental displacementof the cleaning element. The operator then asps the handle 44 and rotates the holder rst m one direction and then in the other, which causes the brush sections to effectually clean or scour the interior walls of the can. Attention is here called to the fact that the periphery of the disk or head 13 oove 34 formed therein for 'the recep-- Pivotally mount is provided with a segmental notch or recess 46 so that the lower rim of the can may be conveniently grasped when ositioning the can within or removing sai can from the holder.

When the can has been thoroughly cleaned the locking member 40 is rotated until the plate 38 is in alinement with the extension 35' and 1n which position the can carrying the brush may be removed from the supporting frame after the clamping band has been released.-

The'machines may be made in different sizes and shapes and constructed of wood, metal or other suitable material.
